我需要禁用BrowseFragment中的标头，然后添加到ArrayObjectAdapter卡。当我做一个setHeadersState(HEADERS_DISABLED)应用程序时会崩溃。如果我setHeadersState(HEADERS_DISABLED)稍后运行方法，例如在onLoadFinished，应用程序不会崩溃，但标题栏立即可见然后隐藏，而不是每次在适配器中显示项目时。

MainFragment.class

 public class MainFragment extends BrowseFragment implements LoaderManager.LoaderCallbacks<List<Module>> {\n        private static final int MODULES_LOADER_ID = 100;\n        private ArrayObjectAdapter mRowsAdapter;\n        @Override\n        public void onActivityCreated(Bundle savedInstanceState) {\n            super.onActivityCreated(savedInstanceState);\n            setupUIElements();\n            setupRowAdapter();\n            setupListeners();\n            getLoaderManager().initLoader(MODULES_LOADER_ID, null, this);\n        }\n            private void setupUIElements() {\n            setTitle(getActivity().getString(R.string.app_name));\n            setBadgeDrawable(getResources().getDrawable(R.drawable.title, getActivity().getTheme()));\n            setHeadersTransitionOnBackEnabled(false);\n            setBrandColor(getActivity().getResources().getColor(R.color.fastlane_background));\n            setHeadersState(HEADERS_DISABLED);\n        }\n            private void setupRowAdapter() {\n            mRowsAdapter = new ArrayObjectAdapter(new ListRowPresenter());\n            setAdapter(mRowsAdapter);\n        }\n            private void setupListeners() {\n            setOnItemViewSelectedListener(new ItemViewSelectedListener());\n            setOnItemViewClickedListener(new ItemViewClickedListener());\n        }\n            private void loadModules(List<Module> …

我有一个片段：

public class FilmFragment extends BrowseFragment implements LoaderManager.LoaderCallbacks<Object>

在BrowseFragment中，添加包含项目的几行：

private void loadRubricsFilms(List<Rubric> mRubrics, List<Film> mFilms) {
    int j = 0;

    for (Rubric mRubric : mRubrics) {
        ArrayObjectAdapter listRowAdapter = new ArrayObjectAdapter(mCardPresenter);

        for (Film mFilm : mFilms) {
            if (mFilm.getRubric() == mRubric.getId()) {
                listRowAdapter.add(mFilm);
            }
        }
        HeaderItem header = new HeaderItem(j++, mRubric.getTitle());
        mRowsAdapter.add(new ListRow(header, listRowAdapter));
    }
    setAdapter(mRowsAdapter);
}

我安装了OnItemViewSelectedListener侦听器：

    private final class ItemViewSelectedListener implements OnItemViewSelectedListener {
    @Override
    public void onItemSelected(Presenter.ViewHolder itemViewHolder, Object item,
                               RowPresenter.ViewHolder rowViewHolder, Row row) …
